Non-volcanic Tremors and Low Frequency Earthquakes in the Alaska-Aleutian Subduction Zone

To study the tremor and LFEs in the Alaska-Aleutian subduction zone, we deployed three mini arrays in the Unalaska island. Using the beam-back projection method, we detect continuous tremor activities and observe different migration patterns both along-strike and dip directions, with various velocities. LFEs and tremors match well with each other spatio-temporally.
